As snd_soc_debugfs_init() is only defined when CONFIG_DEBUG_FS=y, there is no possibility for debugfs_create_dir() returning an error, so remove the unneeded error check.
Removing the error handling means that if in future it does start returning errors we'll ignore them - it's not like the error handling is getting in the way or otherwise causing problems, removing it isn't making things better.
